An alpha particle is identical to a helium atom that has been stripped of its two electrons
<span>A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two.</span>
The answer is System.
When a scientific investigation is in progress, its used to perform and understand the natural phenomenon that goes on using the scientific method. Since this is a descriptive investigation, it provides a descriptive account of any system by looking at it without any prior knowledge to that subject. This method of investigation does not use a hypothesis. Thus, proves our answer correct.
Best of Luck!
Answer:
90.4 mL
Explanation:
Step 1: Given data
- Initial volume of the gas (V₁): 113 mL
- Initial pressure of the gas (P₁): 721 mmHg
- Final volume of the gas (V₂): ?
- Final pressure of the gas (P₂): 901 mmHg
Step 2: Calculate the final volume of the gas
According to Boyle's law, the volume of a gas is inversely proportional to the pressure. We can calculate the final volume of the gas using the following expression.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 721 mmHg × 113 mL / 901 mmHg
V₂ = 90.4 mL
The dependent variable is how far the dogs ran after eating the pills or drinking the water so the correct answer would be D.
